SMA reverse polarity adapter pair Nedis AD/SRP-M:SMA-F — SMA male to SMA female connectors

Pair of Nedis reverse polarity SMA adapters AD/SRP-M:SMA-F convert SMA male to SMA female connectors while maintaining the reversed polarity design. Supplied as two compact coaxial adapters, they enable connection between antennas, cables and devices that use reversed‑polarity SMA interfaces. These adapters are suitable for RF signal paths where a gender change and polarity inversion are required without modifying existing connectors or cables.

Advantages

The adapters provide a simple mechanical solution for connecting mismatched SMA RP interfaces without soldering or cable replacement. Their compact metal body ensures stable mechanical mating and consistent contact alignment, reducing the risk of intermittent connections. Supplied in a pair, they are convenient for simultaneous use on both ends of an extension or to keep as spare parts for networking and RF installations.

Suitable for

• Connecting Wi‑Fi antennas to routers or access points with reversed‑polarity SMA ports
• Adapting GPS antennas to devices with opposite SMA RP gender
• Extending or repairing coaxial RF cables in wireless networking and IoT setups
• Temporary test connections in RF bench work and field diagnostics

Key specifications

• Connector type: SMA reverse polarity (converts SMA male to SMA female)
• Quantity: two adapters per pack
• Material: metal body with plated contacts for reliable conductivity
• Frequency range: suitable for typical RF, Wi‑Fi and GPS frequency bands (practical use up to several GHz)
• Impedance: 50 ohm compatible for standard coaxial RF systems
• Form factor: compact inline adapter for minimal insertion loss and space savings

How to use

To use the adapter, align the SMA RP male connector on the cable or device with the adapter’s SMA RP female end and gently screw them together until hand‑tight. Then attach the adapter’s SMA female output to the SMA male connector of the antenna or second cable in the same manner. Avoid overtightening with tools; hand tightening is usually sufficient to ensure electrical contact and prevent damage to the threads. Use one adapter per connection where a gender/polarity change is required; the pack contains two adapters for dual connections or spares.

Usage recommendations

For best performance, keep connectors clean and free of debris, avoid excessive torque, and use the adapters only in systems compatible with 50 ohm impedance. Do not use adapters as permanent strain relief; secure cables to prevent mechanical stress on the connector interface.
